As the PMIC driver was finally promoved from staging, add the DT
properties for both PMIC and USB3 for HiKey 970.

Add a device tree for the HiSilicon 6421v600 SPMI PMIC, used
on HiKey970 board.
As we now have support for it, change the fixed regulators
used by the SD I/O to use the proper LDO supplies.

Should this be "hisilicon,hi6421-pmic" which is already in the binding document "mfd/hi6421.txt"?
Others are OK to me.

Fine to me and I can merge this patch once the binding for the
"kirin970_hikey_usbhub" and "hi3670-dwc3" are ready.
Thanks!

Fine to me and I can merge this patch once the binding for the
"kirin970_hikey_usbhub" and "hi3670-dwc3" are ready.
Thanks!
Best Regards,
Wei

No.
hisilicon,hi6421-pmic is used by this driver
drivers/mfd/hi6421-pmic-core.c
which provides support for the Hi6421 variants that don't use a MIPI
SPMI bus.
The "hisilicon,hi6421-spmi" compatible is for the new driver:
drivers/mfd/hi6421-spmi-pmic.c
And it is defined at:
Documentation/devicetree/bindings/mfd/hisilicon,hi6421-spmi-pmic.yaml
Both DT bindings and the driver were promoted from staging on this patch:

Whatever works best for you and Greg.
It should be noticed that the driver should be out of staging for v5.15-rc1
(as the patch moving it out of staging was already merged at Greg's tree).
This patch is needed by the PCI driver patchset I'm currently working,
so the best would be if this patch could also be merged for v5.15-rc1
(either via HiSilicon tree or via staging tree).
I suspect that having your ack and merging this via staging would work
best, as this would ensure that both changes will be merged upstream
at the same time.
But, as I said, it is up to you both ;-)
Thanks,
Mauro

Whatever works best for you and Greg.
It should be noticed that the driver should be out of staging for v5.15-rc1
(as the patch moving it out of staging was already merged at Greg's tree).
This patch is needed by the PCI driver patchset I'm currently working,
so the best would be if this patch could also be merged for v5.15-rc1
(either via HiSilicon tree or via staging tree).
I suspect that having your ack and merging this via staging would work
best, as this would ensure that both changes will be merged upstream
at the same time.
But, as I said, it is up to you both ;-)
Thanks,
Mauro

Got it.
To avoid dependency, I think it is better to be merged by Greg's tree.

usb: dwc3: simple: add support for Hikey 970
This binding driver is needed for Hikey 970 to work,
as otherwise a Serror is produced:
It follows the DWC3 schema, e. g.:
Documentation/devicetree/bindings/usb/snps,dwc3.yaml
While double checking for "kirin970_hikey_usbhub", it sounds that
the dt-binding patch was not merged yet, and require further
discussions.
I'll re-start the upstream thread where this was discussed in
the past. I'll re-submit this patch once we finish such
discussions.
